2 Claims. (Cl. 150-05) This invention relates to a new and improved container and method of making the same, and more particularly, to a container which may be used for cosmetics, cigarettes, tools, packaging, and the like. t

I The particular embodiment of the present invention which is illustrated in the drawings and which will be described hereinafter in greater detail, comprises generally, a single sheet of flexible material constituting the front, back and bottom walls, said walls having their end edges turned inwardly for reception in channel sections, and end walls having their edges received in the channel sections.

It is a principal object of the present invention to provide a simple and eflicient means of applying an end wall to a container.

Another object of the present invention is to provide a container having no exposed stitches or other securing means.

Still another object of the present invention is to provide a method of manufacturing a container, of flexible material and requiring no stitching operation.

It is a further object of the present invention to provide a container in which all the walls are fabricated of flexible material and which is self supporting.

Yet a further object of the present invention is to provide a container having a novel top wall closure means.

Still a further object of the present invention is to provide a container wherein a single pair of panel members of any desired configuration will determine the shape of the container.

It is a further object of the present invention to provide a container of the type described which is simple and durable, which is effective for its intended purposes and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is a perspective view of a device constructed in accordance with the present invention and showing the top Fig. 9 is a fragmentary sectional view taken on the line 9-9 of Fig. 1. 1 i

Fig. 10 is a sectional view similar to Fig. 7 showing a slightly modified form of the invention.

Fig. 11 is a sectional view similar to Fig. 8 showing the same slightly modified form of the invention.

Fig. 12 is a sectional view of the front wall of the device taken on the line 1212 of Fig. 1.

Referring now more particularly to the drawings, the embodiment of the invention illustrated therein comprises a container generally designated 20, having a front wall 21, a bottom wall 22, a back wall 23 and a top wall 24. The front, bottom, back,- and top Walls may be fabricated of a single sheet of flexible material 19 as illustrated by the developed view in Fig. 4. The end edges 25, 26 of the single sheet 19 are provided with cutout portions 27 and 28. These cut-outportions or serrations, are illustrated as four in number. The two outer serrations have a curved shape, and the two inner serrations are saw-toothed. Thus, the front edges cannot come together and cause wrinkling. The width of top wall portion 24 is reduced at shoulders 29 and 30 for a purpose to be hereinafter described.

The device may be manufactured by first folding the single sheet to the form shown in Fig. l, and then turning the end edges 25 and 26 inwardly so that the width of the front, bottom, and back walls equals the width of the top wall. As the bottom wall is curved, the cutout portions are necessary to avoid wrinkling of the material when turned inwardly. A pair of U-shaped members 32 having outwardly facing channel sections or grooves 33 are arranged in parallel spaced relation with respect to each other so as to receive the inturned edges 25 and 26.

An end wall 35, as shown in the developed view Fig. 5, is then arranged outwardly of and in covering relation with respect to each of the U-shaped frame members. The end wall 35 is fabricated of flexible sheet material and provided with a plurality of cutouts 36 along its bottom edge 37.

The side and bottom edges of end wall 35 are then turned inwardly and inserted in channel sections 33. It is seen in Figs. 7 and 9 that the inturned edge portions of end Wall 35 and the inturned edge portions of front wall 21 and back wall 23 are arranged in face to face abutting relation with respect to each other.

A force is now exerted to close the channel member and clinch the edge portions therebetween. It is fully appreciated that the edge portions of end wall 35 may be inserted in the channel section 33 prior to the edge portions 25 and 26.

From the foregoing, it is seen that a container is formed of flexible material which is self-supporting, which takes the shape of frame member 32, and which requires no gluing or stitching.

As seen in Fig. 6, the upper edge 38 of end wall 35 extends beyond the free ends 39 of frame member 32. In

order to prevent excessive wear of the exposed edge 38, a bridge-like channel member 40 is arranged to cover the edge 38 and is secured to end wall 35 by crimping. The member 40 also serves to structurally strengthen the end container, by bridging the free ends 39 of frame member 32. For a smoother external appearance, it is preferred to crimp only the inner wall 41 of member 40, leaving the outer Wall 42 undeformed.

The front wall 21 is provided with a curved slit 45 for receiving the free end 46 of top wall 24. In closed position the free end 46 extends beyond the front wall 21 and overlaps the latter.

Extending along the lower edge of slit 45 and secured thereon is a channel member 50. A similar channel 51 extends along and is secured to the free end 46 of top wall 24.

The channels 50 and 51 add rigidity to the container and prevent splitting and fraying of the edges. In addition, the. channels 50. and. 51 cooperate to. form inferengaging lips for positively holding the free end 46 in the slit 45.

In Figs.. 10. and 11, the. use of a lining. 60 adjacent each end wall is shown. The lining 60 is coextensive with the adjacent end wall. 35 and hasits edges 61 and 62 abutting the back and front Walls of the: container. One face of the liner 60 is arranged in abutting relation with respect to the frame 32 and" end Wall 35. The upper edge 63 of lining 60 is secured by channel 40: as shown in Fig. 11.

Another slight modification which is also illustrated in Fig. 1.0, contemplates the use of a bottom wall bar or brace 63; The brace 63 is arranged interiorly of and along. bottom wall 22 and has its ends abutting the liners 60 or. the frame. members 32. This construction has been found. desirable with the use of extremely pliant material to add rigidity to the container.

It is to be understood that this inverted channel frame may be applied to any type of container, regardless of the -1 new, and desire to secure by United States Letters Patent 1 1'. A container comprising a front wall, a back wall spaced from said front wall, a bottom wall connecting said front and back walls, said front, back and bottom walls being fabricated of flexible material, a pair of frames arranged in spaced relation with respect to each other intermediate said front and back walls, each of said frames embracing the adjacent end edge portions of said walls, an end Wall arranged outwardly of and in covering relation with respect to each of said frames, said end walls a being fabricated of flexible material and having their edge portions embracingly received by the adjacent frame, said bottom wall including cut-out portions to avoid wrinkling of the material, a lining arranged inwardly of and in covering. relation. with respect to. each of said frames and secured to the adjacent frame and end wall, and a channel member reinforcement secured over the upper edges of said sidewall and said lining, said channel member being secured by crimping the inner edge thereof to the wall of the container.

2. A container comprising a front wall, a back wall spaced from said front wall, a bottom wall connecting said front and back walls, said front, back and bottom walls being fabricated of flexible material, a pair of frames arranged inspaced relation with respect to each other intermediate said front. and back walls, each of said frames embracing the adjacent end edge portions of said walls, an end wall arranged outwardly of and in covering relation with respect to each of said frames, said end walls being fabricated of flexible material and having their edge portions embracingly received by the adjacent frame, channel member reinforcing means crimped on said walls, a top wall fabricated of flexible material having one end connected to saidback wall and the other end extending beyond said front wall, said front wall being provided with an opening for receiving the extending end. of said top wall, and channel members forming interengaging lips on said front wall and said extending. end for holding said extending end in said opening.
